High-Capacity Iskratel Lumia OLTs

High-capacity OLTs

provide multi-gigabit FTTH access from multi-blade shelves of various sizes that address all deployment densities for XGS-PON, GPON, 10GE P2P, 50G-PON and 100G-PON.

Super-scalable next-generation OLTs with a terabit backplane guarantee the return and safety of investment with the longest lifespan across present and future FTTH technolo­gies.

Iskratel Lumia family of shelf-based OLTs

High-capacity Iskratel Lumia OLTs are scalable, high-performance fibre OLTs that connect end users over a variety of PON and P2P technologies from a single, cost-effective platform.

Iskratel Lumia OLTs fit all deployment densities, from high-density urban to low-density rural areas, while various shelf options and interfaces address every use case in the fibre-access network.

The outstanding switching, backplane and uplink capacities make Iskratel Lumia OLTs ideal to host all present and future PON and P2P technologies, from XGS-PON, GPON and 10GE P2P to 50G-PON and 100G-PON.

The super-long lifespan is further facilitated by the dual nature of Iskratel Lumia OLTs: sup­porting conventional and virtualised operation on the same hardware, they allow operators to skip entire investment cycles.

Fully compliant with the EU’s Code of Conduct on Energy Consumption of Broadband Equipment, the energy-saving Iskratel Lumia OLTs help operators cut energy bills and reduce the impact on the environment.


  • Support for a multitude of present and future FTTH technologies, such as XGS-PON, GPON, 10GE P2P, 50G-PON and 100G-PON.
  • Flexible shelf configurations for different capacities, with up to 14 slots in a shelf.
  • Support for all types of residential, business, or cloud-based services.
  • Up to 800 Gbps per subscriber blade, with dual-star backplane.
  • Up to 1.4 Tbps uplink connectivity.
  • Industry-leading temperature range from –40 °C to +65 °C.
  • Seamless transition to virtualised, SDN-powered fibre access.
  • Support for multi-provider deployment scenarios, including virtual unbundling and open access.

Iskratel Lumia T14 – High-density shelf-based OLT

Iskratel Lumia T14 is a 14-slot, multi-terabit OLT with terabit-capable backplane. It provides flexible port configuration with Combo (for XGS-PON, GPON and 10GE P2P) or 25G/50G-PON subscriber blades, while its scalable density makes it ideal for deployment in central offices, street cabinets or buildings.

Fully equipped with Combo OLT subscriber blades, Iskratel Lumia T14 provides FTTH connectivity to more than 50,000 users over 208/192 ports of a single OLT.

With 400 Gbps per subscriber blade and switching capacity of 3.4 Tbps, Iskratel Lumia T14 is able to host present and future PON technologies in a super-scalable, high-density OLT.

Faster, greener and more sustainable connectivity

At the forefront of FTTH innovation, Iskratel Lumia T6 features low TCO and super-long lifespan thanks to:

  • Capacities that support present and future FTTH technologies, from GPON/XGS-PON to 50G/100G-PON;
  • Dual nature that enables conventional and virtualised (SDA) operation on the same hardware;
  • Ability to host a virtualised BNG (vBNG) and act as a service edge without hardware upgrade;
  • Low energy consumption that fuels operators’ sustainability strategies, reduces the environmental impact and cuts energy bills.


Universality and sustainability

The high-capacity Iskratel Lumia OLTs are unique “amphibious” OLTs, able to operate in conventional mode or in virtualised SDA (Software-Defined Access) environment. Their unique dual nature lets operators virtualise and cloudify the network without hardware replacement, allowing them to skip an entire investment cycle while introducing software-defined, next-generation broadband access.


  • Two characters: conventional and virtualised.
  • One amphibious box.
  • Zero hardware upgrade.


Seamless transformation

Unlike other OLTs in the market, Iskratel Lumia OLTs can host a distributed, virtualised BNG (Border Network Gateway) to take care of automated provisioning and accounting for the services you provide to customers, and cut the costs of your infrastructure for years to come.

With embedded vBNG, Iskratel Lumia OLTs make the perfect choice for anyone who needs a flexible, extensible and future-proof solution. As Iskratel Lumia Edge OLTs, these top-of-the-line programmable OLTs protect the existing investments and make production life simpler while keeping up with future demands.
